Changes to the management of footrot in South Australia will be phased in from July 2018.
Changes to the program that producers should note:
- National Vendor Declarations (NVDs) and National Sheep Health Declarations (NSHDs) are still compulsory.
- There will be increased ability for infected producers to trade sheep. Buyer beware means you need to check the status of animals BEFORE you purchase – check the NVD and NSHD.
- Movement restrictions into SA remain in place.
What is footrot
Footrot is a contagious bacterial disease in sheep.
It can cause significant economic loss to producers through reducing:
- ewe fertility
- wool growth
- growth rates
- sheep sales.
Controlling or eradicating footrot is very costly.
Footrot is a notifiable disease and must be reported immediately. See the reporting animal disease page for instructions.
When a flock has footrot
If a flock has been detected with very virulent strains of the bacteria there are movement restrictions that can be enforced under the South Australian Livestock Act 1997.
When there is a suspicion a flock has very virulent strains of the Footrot bacterium, sheep:
- cannot be sold to other graziers
- must not be sold in a public market
- must not be allowed to stray onto public roads or neighboring properties.
Sheep with footrot can be sold directly to an abattoir for slaughter.
Footrot detection trial underway
Biosecurity SA is speeding up the detection of footrot through a statewide 12 month trial into the cutting edge loop mediated isothermal amplification or LAMP diagnostic process. LAMP is a portable diagnostic technology that uses a single tube technique for the amplification of DNA.
LAMP is an on-farm test that can give a diagnosis within 20 to 30 minutes. Results from currently available laboratory test processes can take several weeks.
As part of the trial, Biosecurity SA Animal Health officers will compare the LAMP process to other existing disease technologies.
While this current trial focuses on footrot LAMP can also be used for other animal and plant disease detection, depending on the availability of suitable reagents.
